Strain Gage Instrumentation for Analysis of Trusses and Other Mechanical Assemblies

该项目要求学生对桁架组件和不同几何形状的构件进行非破坏性的实验室工作，以验证课堂问题解决所预测的载荷和挠度。实现包括构造针连接桁架模型和具有不同几何形状的机器部件。这些仪器配有应变片和适当的读数设备，以显示桁架中的载荷分担和分布以及应力集中因素的现象。该项目允许学生在实验室中操作物理模型来演示现在仅依赖于解决问题的主题。

This project has students perform nondestructive laboratory work on truss assemblies and members of varying geometry to verify loads and deflections that were predicted by classroom problem solving. Implementation includes the construction of pin-connected truss models and machine components with varying geometry. These are instrumented with strain gages and appropriate readout equipment in order to demonstrate load sharing and distribution in trusses and the phenomena of stress concentration factors. The project permits the student to manipulate physical models in the laboratory to demonstrate topics that now rely solely on problem solving.
